'12 Claims. (01259-122) This invention relate's'to improvements in coolersv of a type that may be applied to the top of a can or container and spray around the can or container a liquid.

. It is moreparticularly the object of this invention to provide an instrumentality that may be placed over the mouth of the container and distribute about the container and over the surface thereof a liquid and break the liquid'upfl into fine sprays" and cause these fine sprays to impinge upon the surface of the container.

It is'also the object of this invention to provide a cooling instrumentality.operated by a source of water under pressure, to atomize the water, disrtribute the water about the surface of a conrial in the container will be. brought in contact with the inner surface of the container by means of a current produced therein.

These and other advantages will be apparent from the following descriptiontaken in connection with the drawings, inwhich: I

, The cooler as a whole is composed of four parts: annular base member I, an. lnner'support member 2, a cap member 3, and arotor 4; which is somewhat bell-shaped. The base member, the support member, and the cap member form a. housing, "the lower part of which housing forms an annular water chamber. The annular a vertical flange 6. Extending upwardly from theinner edge of the base member is a plurality of projections l, slightly spaced apart to provide notches 8 through which water or other cooling fluid is sprayed. Extending outwardly from many of the projections 1 toward the flange 6 are fins 9, which are arranged at an acute angle to the radii of the base member. Each fin adjacent its projection 1 is reduced in size so that it extends above the inner. surface of the hori- 1'9 zontal' part5 only a small distance. This reduced part of each fin is indicated by themimeral l0. The annular member is provided with a plurality of bosses II with screw holes l2 therein to receive screws l3 by which the support memberZmay be attached to the annular member l.- For-receiving these screws, the support member is provided with bosses It For the purpose of introducing water into the cooler the flange 6 has therein. an opening I 5 into the water 20 chamber; around which is an inlet spout l6 ar- "ranged to project at an acute angle to the radius of the base member passing through the open- I ing l5. Extending from the upper edge of the flange 6, is a plurality of bosses ll with holes I8 25 therein. The support member has an inner downwardly extending spout'*-l9, adapted to fit within the mouth of the container such as a milk can to support the whole cooling apparatus on the container. Extending fromv the top edge of 3,0. the spout IS, the support member has an outwardlyand downwardly extendingpart 2D with arcuate slots 2| therein adjacent spout IS. The outer part of the support member consists. of a vertical wall part 22 adapted to engage the base member at the parts Ill between the projection 1. Figure 3 is a top plan view of an annual base it and the fins 9.. In this structure there is provided small passageways between the annular member and the support member at the lower parts of the notches 8. On the part 20 of the 40 support member and between the spout l9 and the vertical wall part 22 are equally spaced ribs 23which have notches 24 therein which serve to stabilize and position the cooler on top of the container or can, such as a milk can.

The cap member 3 has an annular flange 25 adapted to fit Within the flange 6 of the base member and has an overhanging lip: 26 which engages and extends over the upper surface of the annular flange 6. For the purpose of at- 0 taching the cap member to the annular base member there is provided on the cap member a plurality of lugs 2'! withholes; therein to receive screws 28 which are threaded into the holes I8 of the lugs l! on the base member. The flange 25 is' provided with a notch 29 opposite the open-' ing l so as to provide a passageway from the spout I 6 into the cooler. The central part of the cap member 3 is depressed as indicated by the numeral 30 and has therein a central opening 3| around which there is an upwardly extending flange 32 and a horizontal flange 33. These flanges provide a support for one member 3d of a raceway. The cap member 3 in the depressed part has a plurality of. slots 35v ar ranged around the flange 32.

Supported by the cap member and rotating between the cap member and the support memrotated adjusted with relation to cap member and the whole cooling apparatus. This adjustability is for purpose of adapting the cooler to cans of various sizes, such as, 3, 5 or gallon cans. On the lower end of the shaft M] are stirrer blades 43- which may be made of Bakelite of any other suitable material and which is suitably attached to the shaft 4t which is made of stainless steel.

Extending horizontally from the hollow stem, there is a horizontal portion 44 of the stirrer which passes into an annular decline portion 45 and into a vertical portion 46. In the horizontal portion of the stirrer there is a plurality of slots ill and adjacent each slot is an arcuate rib 418. Each rib extends from the inner edge of one slot to and about the outer edge ofanother slot and terminates adjacent to but spaced from an annular flange 39 at the'outer edge of the horizontal portion of 44 of the rotor. This flange 49 ex tends around a flange 50 extending downwardly from the cap member 3. The slots All and 35 serve asoutlets from the container so that any heated air therein may readily escape. 'The parts 48', 49, and 50 act as bafiies to prevent water orany other cooling liquid from passing into the can or container through the spout l9. Around the outer surface of the vertical portions 36 of the rotor is a plurality of inclined blades 5! against which the liquid passing through the spout l5 impinges whereby the rotor is rotated. These blades are arranged about one inch apart and serve to break the stream of water up as well as to rotate the rotor and further these fins are so arranged that they tend to force the water accumulating in the base member downward and inward beneath the rotor through the notches 8 in fine sprays in which the water is separated into minute particlesand are distributed over the outer surface of the can or container-to which the cooler is attached. To conduct any water that might accumulate in the upper edge of the space between the rotor and the cap member there is provided in the portion 45 of the rotor a plurality of troughs 52, each of which has an inwardly extending rib 53 on the innerside and under of the portion 45. While the throughs 52 aid in returning water collecting between the cap and the rotor downward towardfins 55, the ribs 53 serve to prevent any water accumulating between the rotor and thesupport member from passing into spout l9. The Water accumulating The.

in the space between the rotor and the support apparatus is connected to a source of water pres-.

sure by means of the spout I6 and the pressure is applied, the rotor is caused to rotate carrying with itthe stirrer. The water which operates the rotor passes beneath the rotor through the notches 8 where it is divided into fine sprays and caused to impinge upon the surface of the ca-nor container. This water being finely sprayed upon the surface of the can tends to absorb heat more rapidly and the stirrer provides a current in the contents of the can, rather than an agitation of said contents.

It has been found from actual practice that,

i when this cooler is applied to a can of milk, the

temperature of thernilk within the can may bereduced in fifteen minutes to within four degrees I to the temperature of the water sprayed. It is also possible'with the use of the present apparaw tus after the animal heat has been removed out of the milk to flash pasteurize the milk in the can by the use of hot water instead of the cold Water.

This apparatus may be attached to the cans and container of various sizesj'lhree adjustments have been shown but it is to be understood that the extent of the application of the apparatus is not to. be limited in any manner by this showing. The degree of the agitation may be varied by varying the pitch ofthe blades 43. It."

is not the purpose of this apparatus that the milk or other material bestirred but it is the purpose.

of this invention that the materialbe caused to move from the center of container to the surtace and from the surface to the center thereof.
